The North American Aerospace Defense Command Cheyenne Mountain Complex is to receive sustainment services from Raytheon.

The services, as well as products, will be provided until March 30, 2020, under an indefinite-delivery/indefinite-quantity award worth $700 million, the company said.

"Raytheon has deep expertise in sustainment and modification solutions that include sensor and software systems, radars, command and control, and range-engineering services," said David Wajsgras, president of Raytheon Intelligence, Information and Services. "We look forward to working closely with the Air Force in this important area of national security."

NORAD is a combined U.S.-Canadian military organization that provides air defense and warning capabilities for the North American continent. It is based at Peterson Air Force Base in Colorado and operates an alternate command center in a nuclear bunker inside Cheyenne Mountain.

Raytheon said that under the contract it will provide sustainment services and products supporting the Integrated Tactical Warning/Attack Assessment and other systems to enable accurate, timely and unambiguous warning and attack assessment of air, missile and space threats. The work will be conducted at Peterson, AFB, Peterson AFB; Cheyenne Mountain Air Force Station; Vandenberg AFB, Calif.; and Offutt AFB, Neb.
